Learning Outcomes
After completing the course, the student knows how to - describe the structure of satellite positioning system and explain the tasks of the segments - describe the structure of positioning signal and explain the properties of the signal components - describe the structure of a satellite navigation receiver and explain the tasks of the main functional blocks - classify the error sources of positioning measurements and estimate their effect on positioning accuracy - form a geometry matrix and use it to obtain position estimate - define the coordinate frames important in satellite positioning, transform coordinates between the systems

Instructions for students on how to achieve the learning outcomes
Grading is based on the final exam. For grades 1-2 the core content is enough, for grades 3-4 substantial knowledge on the deeper topics is needed. For grade 5, most of the material of the course has to be mastered.
